Classical mechanics is a branch of physics that deals with the motion of bodies under the influence of force, providing a framework for understanding the physical world from the macroscopic to the astronomical scale. It is based on principles such as Newton's laws of motion and the conservation of energy, serving as the foundation for more advanced theories like quantum mechanics and relativity.

The macroscopic scale refers to the level at which objects and phenomena are large enough to be visible and measurable without the aid of a microscope, encompassing the everyday world we interact with. It contrasts with the microscopic scale, where quantum and molecular interactions dominate, and is essential in fields such as classical mechanics, thermodynamics, and fluid dynamics.

Macroscopic Scale

astronomical scale

Newton's laws of motion form the foundation of classical mechanics, describing the relationship between a body and the forces acting upon it, and its motion in response to those forces. These laws explain how objects move and interact, providing a framework for understanding everything from everyday phenomena to complex engineering systems.

Newton's laws of motion

The conservation of energy principle states that energy cannot be created or destroyed, only transformed from one form to another or transferred between objects. This fundamental concept underpins all physical processes and is a cornerstone of both classical and modern physics, ensuring that the total energy of an isolated system remains constant over time.

advanced theories

Quantum mechanics is a fundamental theory in physics that describes the physical properties of nature at the smallest scales, such as atoms and subatomic particles. It introduces concepts like wave-particle duality, uncertainty principle, and quantum entanglement, which challenge classical intuitions about the behavior of matter and energy.

quantum mechanics

Relativity, formulated by Albert Einstein, revolutionized our understanding of space, time, and gravity, demonstrating that the laws of physics are the same for all observers and that the speed of light is constant regardless of the observer's motion. It consists of two theories: Special Relativity, which addresses the physics of objects moving at constant speeds, and General Relativity, which extends these principles to include acceleration and gravity, describing gravity as the curvature of spacetime caused by mass.
